What Custom Viewer will you create?

Most developers spend hours building products, but when something breaks, they end up spending even more time inspecting raw network traffic and digging through endless JSON payloads.

That's why we built Custom Viewers in NetworkSpy.

Instead of forcing your team to interpret the same traffic differently every time, Custom Viewers let you transform raw requests and responses into visualizations tailored to your application and workflow.

With Custom Viewers, teams can:

• Turn complex API traffic into timelines, dashboards, and domain-specific views
• Visualize AI agent loops, tool calls, and execution flows
• Highlight the data that matters while hiding noise
• Share and version viewers across the team for consistent debugging workflows
• Reduce the time spent manually parsing payloads and logs

The biggest benefit isn't just faster debugging.

It's reducing cognitive load.

Developers shouldn't have to reconstruct application behavior from thousands of lines of JSON every time they investigate an issue. The tooling should do that work for them.

Network traffic already contains the answers. Custom Viewers help you see them.
